Countersunk Head Bolt Description

Countersunk bolts are used when a smooth surface is required. Common applications include: bridge decking, walkways, and railing.
A countersunk screw is a type of fastening that sits flush with the surface of the material it occupies. These screws typically are used so that you can cover them easily with either a screw cap or piece of wood. ... The typical angle of a countersunk screw head is 82 degrees, but this varies depending on the application.
